Specific embodiment
The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below:
Fig. 1, Fig. 2 and Fig. 3 are please referred to, hollow object slot stamping die includes upper die component 10, discharging mold insert 20, punch-pin knife
The fixed mold insert 40 of piece 30, cavity plate, plug 50, lower mold assemblies 60 and mistake proofing protective device 70.
Upper die component 10 includes upper die holder 12, punch retainer 14, spring 16 and stripper 18.Upper die holder 12 and punch-pin are solid
Fixed board 14 is fixedly connected, and punch-pin blade 30 is fixed on punch retainer 14, and stripper 18 passes through spring 16 and punch retainer
14 connections.Discharging mold insert 20 is fixed on stripper 18, and stripper 18 offers perforative slot, and discharging mold insert 20, which offers, to be passed through
The upper slot worn, punch-pin blade 30 pass through the slot of stripper 18 and the upper slot punching press hollow object to be processed of discharging mold insert 20
Side, spring 16 compresses at this time, and after completing punching press, spring 16 resets, and 30 return of punch-pin blade is deviate from from hollow object.
Lower mold assemblies 60 include lower die holder 62 and limited post 64.The fixed mold insert 40 of cavity plate is fixed on 62 center of lower die holder
On, limited post 64 is fixed on 62 side of lower die holder.When mold clamping, limited post 64 is abutted with upper die component, completes limit
Effect.
Plug 50 opens up grooved hole, the slot position consistency that the slot on plug 50 need to be opened up with hollow object to be processed, and
Slot on plug 50 is slightly larger than the slot that hollow object to be processed need to open up.Plug 50 is placed in hollow object to be processed, plug
50 support with hollow object inner wall.Discharging mold insert 20 offers upper groove 22, and the fixed mold insert 40 of cavity plate offers corresponding lower groove
42, hollow object to be processed is placed in the gap that upper groove 22 and lower groove 42 cooperate, in 22 inner wall of upper groove and lower groove 42
Wall supports the outer wall of hollow object to be processed.Plug 50 supports progress one inside hollow object to be processed, and 22 He of upper groove
The cooperation of lower groove 44 to a support is carried out outside hollow object to be processed, so hollow object to be processed be stamped when
Wait, would not easily deformation or damage, improve machining accuracy.
Punch-pin blade 30 includes guide part 32 and blade portion 34, and guide part 32 is fixedly connected with blade portion 34.Blade portion 34
The contact jaw 342 of punching press hollow object to be processed is oblique, reduces the contact area of contact jaw 342 Yu hollow object, in this way may be used
To reduce the blanking pressure between blade portion 34 and hollow object.So, it is multiple can disposably to install fixation for upper die component 10
Punch-pin blade 30 realizes that opening up for the requirement slot of hollow object is completed in a punching press, improves processing efficiency.
Guide part 32 is abutted with the inner wall of upper groove 22 and lower groove 42, when 34 punching hollow part side of blade portion,
Guide part 32 is moved along the inner wall of upper groove 22 and lower groove 42, is on the one hand on the other hand led for 34 punching press of blade portion guiding
It is that blade portion 34 provides holding power to portion 32, for balancing the side blow power generated when its punching hollow part side.Guide part simultaneously
32 thickness are wider than blade portion 34, enhance the integral strength of punch-pin blade 30.
Mistake proofing protective device 70 is fixed on lower die holder 62.Mistake proofing protective device 70 includes cylinder 72 and holding piece 74.Gas
The drive rod of cylinder 72 is fixedly connected with holding piece 74, and hollow object to be processed offers card slot, and holding piece 74 is equipped with corresponding convex
It rises, the drive rod of cylinder 72 pushes holding piece 74, and the side that is not stamped with hollow object of holding piece 74 abuts, the protrusion of holding piece 74
Match with hollow object card slot.Realize the positioning of hollow object to be processed.
Microswitch is housed on the drive rod of cylinder 72 simultaneously.Whether the driving thick stick of jogging switches measurement cylinder 72 is with regulation
Stroke push holding piece 74, guarantee holding piece 74 can correctly be abutted with hollow object, it is therefore prevented that caused because of operation error
The problem of burn failure.Since cylinder 72 pushes the top of holding piece 74 to hold hollow object to be processed, in this way in hollow object to be processed
When side is stamped, supporting piece can balance hollow object to be processed and not be stamped the lateral force of side.So that sky to be processed
Heart part stress balance and position are stablized, and such punch-pin blade and the plug edge of a knife are just not easy to damage because of force unbalance.
In the present embodiment, condenser collecting pipe partition slot needs to open up 12, then corresponding punch-pin blade 30 has 12
It is a, while the gap that upper groove 22 and lower groove 42 cooperatively form is corresponding with condenser collecting pipe shape.
Evaporator D type pipe partition slot needs to open up 3, then corresponding punch-pin blade 30 has 3, while upper groove 22
It is corresponding with evaporator D type pipe shape with gap that lower groove 42 cooperatively forms.
Plug is mounted on lower mold assemblies, grooved hole on plug.Have on the fixed mold insert of cavity plate corresponding through slot
Hole.After needing the hollow object tubing of punching press to be mounted on plug, under the action of punching machine, when upper and lower mould is closed, punch-pin blade, core
3 crucial edge of a knife parts of stick and the fixed mold insert of cavity plate complete punching work jointly.
Mold processing improves accurate to dimension and stability, dimensional tolerance required precision is promoted to by ± 0.15 ±
0.05, substantially increase the solder yield and reliability of condenser and evaporator.Mold can once process 10 slots with
On, clamping, pickup time are shorter, 100% or more improved efficiency.And mold processing hole bur is small, has saved artificial removal's burr
Time.In addition only using a small amount of volatile oil, processing cost is greatly reduced, and safer, more environmental.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
